ABSTRACT

In an approach for converging a cloud computing environment and a mobile device into an integrated environment, a processor receives a request to complete a computing task on a first device, wherein the computing task requires a physical sensor. A processor determines that the computing task should be offloaded from the first device to a second device based, at least in part, on the first device lacking the physical sensor and the second device having the physical sensor. A processor offloads the computing task from the first device to the second device. A processor receives a result of the computing task from the second device.

BACKGROUND

The present invention relates generally to the field of mobile and cloud computing, and more particularly to real-time resource identification and monitoring to determine whether to offload a computing task from mobile to cloud or cloud to mobile.

Mobile computing is human-computer interaction by which a computer, transmitting data, voice, and video, is expected to be transported during normal usage.

Cloud computing is a kind of Internet-based computing that provides shared processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services), which can be rapidly provisioned and released with minimal management effort. Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers. Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to a utility (e.g., the electricity grid) over a network.

DETAILED DESCRIPTION

Embodiments of the present invention recognize the growing amount and variety of computing tasks asked of cloud computing environments and mobile devices. In some instances, a cloud computing environment or mobile device can become overloaded with computing tasks, and then performance in completing these computing tasks will suffer. In other instances, a cloud computing environment or mobile device may not have the needed resource, such as a sensor, to complete a computing task. Embodiments of the present invention provide solutions by identifying capabilities and monitoring current resource utilization of mobile devices and cloud computing environments. Based on this, as discussed in greater detail herein, embodiments of the present invention determine whether to offload a computing task from a mobile device to a cloud computing environment, from a cloud computing environment to a mobile device, and from a mobile device to a cloud computing environment to a different mobile device to provide enhanced performance of cloud computing environments and mobile devices. This integrated computing environment enables on-demand sharing of resources and on-demand load sharing capabilities between a cloud computing environment and mobile devices.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, cnetworks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

The present invention will now be described in detail with reference to the Figures.

In FIG. 1, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 includes one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 1 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

FIG. 3 is a functional block diagram illustrating a computing environment 100, in accordance with an embodiment of the present invention. FIG. 3 provides only an illustration of one embodiment and does not imply any limitations with regard to the environments in which different embodiments may be implemented.

In the depicted embodiment, computing environment 100 includes cloud computing environment 102, mobile device 104, and mobile device 106 interconnected over a network (not shown). The network may be a local area network (LAN), a wide area network (WAN) such as the Internet, the public switched telephone network (PSTN), any combination thereof, or any combination of connections and protocols that will support communications between cloud computing environment 102, mobile device 104, and mobile device 106, in accordance with embodiments of the invention. The network may include wired, wireless, or fiber optic connections.

Cloud computing environment 102 operates to complete computing tasks and includes adaptive system program 108 a. Cloud computing environment 102 functions as described hereinabove in the FIG. 1 and FIG. 2 descriptions. Cloud computing environment 102 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Mobile device 104 operates to complete computing tasks and includes adaptive system program 108 b. Mobile device 106 operates to complete computing tasks and includes adaptive system program 108 c. Mobile device 104 and mobile device 106 can be laptop computers, tablet computers, smart phones, or any portable programmable electronic device capable of receiving and sending data and communicating with each other via a network. In general, mobile device 104 and mobile device 106 are representative of any electronic devices, or combination of electronic devices, capable of executing machine-readable program instructions, as described in greater detail with regard to FIG. 5. Computing environment 100 may include additional computing devices, servers, computers, mobile devices, or other devices not shown.

Adaptive system program 108 a, 108 b, and 108 c collectively operate to determine whether a computing task should be offloaded based, at least in part, on current resource utilization and device capability. Adaptive system program 108 refers to an instance of adaptive system program, generally, while 108 a, 108 b, and 108 c refer to adaptive system program running on a specific local computing device or specific computing environment, as depicted in FIG. 3. In the depicted embodiment, adaptive system program 108 a identifies capabilities of cloud computing environment 102 and monitors the current resource utilization of cloud computing environment 102. In the depicted embodiment, adaptive system program 108 b identifies capabilities of mobile device 104 and monitors current resource utilization of mobile device 104. In the depicted embodiment, adaptive system program 108 c identifies capabilities of mobile device 106 and monitors current resource utilization of mobile device 106. A resource of a cloud computing environment or mobile device may include, but is not limited to, its CPU, memory, battery, network, and sensors. In some embodiments, when adaptive system program 108 receives a request to complete a computing task, adaptive system program 108 determines whether the computing task should be offloaded based, at least in part, on device capability and current resource utilization. In some embodiments, adaptive system program 108 resides on cloud computing environment 102, mobile device 104, and mobile device 106. In other embodiments, adaptive system program 108 may reside on another cloud computing environment, or another mobile device (not shown), provided that adaptive system program 108 has access to location identifying information associated with cloud computing environment 102, mobile device 104, and mobile device 106.

Sensor 110 operates to measure physical qualities associated with a mobile device or cloud computing environment. A sensor measures physical qualities such as, but not limited to, temperature, light, heat, pressure, sound, and location. Sensor 110 is a resource that is identified by adaptive system program 108. In the depicted embodiment, sensor 110 is located on mobile device 106 and measures physical qualities associated with mobile device 106. In some embodiments, sensor 110 may reside on cloud computing environment 102, mobile device 104, and mobile device 106. In other embodiments, sensor 110 may reside on another cloud computing environment, or another mobile device (not shown).

FIG. 4 depicts a flowchart 200 of the steps of adaptive system program 108 executing within converged cloud and mobile environment of FIG. 3, in accordance with an embodiment of the present invention. In the depicted embodiment, adaptive system program 108 operates to determine whether a computing task should be offloaded based, at least in part, on device capability and current resource utilization.

In step 210, adaptive system program 108 receives a request to complete a task. In the depicted embodiment, for example, adaptive system program 108 receives a request to complete a computing task on cloud computing environment 102, mobile device 104, or mobile device 106. A computing task, or task, can be, but is not limited to, a unit of execution, unit of work, unit of computation, set of actions, process, step, request, or query for work. For example, when a user of mobile device 104 selects a weather application icon, adaptive system program 108 b receives a request on mobile device 104 to open the weather application and generate the weather forecast for the user's current location. In some embodiments, completion of a task may require completion of multiple units of execution, units of work, units of computation, sets of actions, processes, steps, requests, or queries for work. For the weather application example, generating the weather forecast for the user's current location entails determining a current temperature for the city, a daily forecast for the city, and generating a current precipitation radar map for the city. In some embodiments, a task requires a sensor, such as sensor 110, to complete the task. For the weather application example, generating the weather forecast requires a temperature sensor to determine the current temperature of the user's current location.

In step 220, adaptive system program 108 identifies and monitors resources while processing the task. In the depicted embodiment, adaptive system program 108 identifies the resources of cloud computing environment 102, mobile device 104, and mobile device 106. In the depicted embodiment, adaptive system program 108 monitors the resources of cloud computing environment 102, mobile device 104, and mobile device 106. In some embodiments, adaptive system program 108 monitors, in real-time, the usage and availability of resources on cloud computing environment 102, mobile device 104, and mobile device 106. For the weather application example, adaptive system program 108 b will identify and monitor in real-time the usage and availability of resources on mobile device 104.

In some embodiments, adaptive system program 108 processes a task by identifying the individual units or steps of the task. In some embodiments, adaptive system program 108 identifies what resources are needed to complete each unit of the task. For the weather application example, adaptive system program 108 b will process the request to determine the current temperature for the city, generate a daily forecast for the city, and generate a current precipitation radar map for the city. Adaptive system program 108 b will identify three units of the task as (1) determining the current temperature for the city, (2) generating a daily forecast for the city, and (3) generating a current precipitation radar map for the city. Then, adaptive system program 108 b will identify what resources are needed for these units of the task.

In decision 230, adaptive system program 108 determines whether the task should be offloaded. For a task that includes multiple units, adaptive system program 108 will determine whether each unit of the task, separately, should be offloaded. In this embodiment, adaptive system program 108 determines whether to offload the task based, at least in part, on the identification of required resources and the monitored current resource utilization (see step 220). Reasons to offload a task include, but are not limited to, an overloaded processor, low battery power, data usage limits, and lack of a required type of sensor to perform the task. For the weather application example, adaptive system program 108 determines that mobile device 104 lacks the required temperature sensor to generate the weather forecast, therefore, the task should be offloaded. If in decision 230, adaptive system program 108 determines the task should be offloaded, then, adaptive system program 108 will offload the task (see step 240). If in decision 230, adaptive system program 108 determines the task should not be offloaded, then, adaptive system program 108 will determine whether the processing of the task has been completed (see decision 260).

Continuing the weather application example, if adaptive system program 108 b determines from monitoring mobile device 104 that mobile device 104 has a low battery, adaptive system program 108 b may determine that the computing task of generating the radar map should be offloaded to cloud computing environment 102. This may, for example, conserve battery life by reducing processor utilization. Then, if adaptive system program 108 a determines from monitoring cloud computing environment 102 that cloud computing environment 102 does not have the necessary type of sensor (e.g., a temperature sensor) to determine the current temperature for the city, adaptive system program 108 a will offload the computing task of determining the current temperature to mobile device 106, which does have the necessary type of sensor, sensor 110.

In step 240, adaptive system program 108 offloads the task. In some embodiments, adaptive system program 108 uses remote method invocation to offload the task to a cloud computing environment or mobile device. Remote method invocation allows objects to access data and invoke methods on remote objects. In some embodiments, adaptive system program 108 uses dynamic remote method invocation, which is a method that is calculated at runtime then defined, to offload the task to a cloud computing environment or mobile device. In some embodiments, adaptive system program 108 can automatically filter, reconstruct, and deploy a task's functional unit code to a cloud computing environment or mobile device. In a first embodiment, where the task originated on mobile device 104, adaptive system program 108 b offloads the task to cloud computing environment 102. In a second embodiment, where the task originated on cloud computing environment 102, adaptive system program 108 a offloads the task to a mobile device, which, in this embodiment, could be mobile device 104 or mobile device 106. In a third embodiment, where the task originated on mobile device 104, adaptive system program 108 b offloads the task to cloud computing environment 102, and then, adaptive system program 108 a offloads the task to mobile device 106. For the weather application example, adaptive system program 108 b offloads the computing task of generating the weather forecast to cloud computing environment 102. Then, adaptive system program 108 a offloads part of the task, determining the current temperature of the city, to mobile device 106, which has the necessary type of sensor, sensor 110.

In step 250, adaptive system program 108 receives a result. In the first embodiment, adaptive system program 108 b receives a result of the task from cloud computing environment 102. In the second embodiment, adaptive system program 108 a receives a result of the task from mobile device 104 or mobile device 106. In the third embodiment, adaptive system program 108 a receives a result of the task from mobile device 106, and then, adaptive system program 108 b receives the result of the task from cloud computing environment 102. For the weather application example, adaptive system program 108 a receives the current temperature of the city from mobile device 106 and adaptive system program 108 a sends the current temperature data to mobile device 104 where the user, who originally requested the task, can view the current temperature in the weather application.

In decision 260, adaptive system program 108 determines whether the processing of the task has been completed. In some embodiments where the task is made up of several units of work, adaptive system program 108 can determine whether all the units of work have been completed or whether it needs to determine whether another unit of work should be offloaded. If, in decision 260, adaptive system program 108 determines the processing of the task has been completed (decision 260, yes branch), then, adaptive system program 108 will end. Adaptive system program 108 may determine that the processing of the task has been completed if, for example, the task is the execution of a computer program and the computer program has completed execution, or has been closed. If in decision 260, adaptive system program 108 determines the processing of the task has not been completed (decision 260, no branch), then adaptive system program 108 will proceed to continue to identify and monitor resources while processing the task (see step 220). Adaptive system program 108 may determine that the processing of the task has not been completed if, for example, the task is the execution of a computer program and the computer program continues to execute.

FIG. 5 depicts a block diagram of components of computing environment 100 in accordance with an illustrative embodiment of the present invention. It should be appreciated that FIG. 5 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made.

Computing environment 100 includes communications fabric 502, which provides communications between computer processor(s) 504, memory 506, persistent storage 508, communications unit 510, and input/output (I/O) interface(s) 512. Communications fabric 502 can be implemented with any architecture designed for passing data and/or control information between processors (such as microprocessors, communications and network processors, etc.), system memory, peripheral devices, and any other hardware components within a system. For example, communications fabric 502 can be implemented with one or more buses.

Memory 506 and persistent storage 508 are computer-readable storage media. In this embodiment, memory 506 includes random access memory (RAM) 514 and cache memory 516. In general, memory 506 can include any suitable volatile or non-volatile computer-readable storage media.

Adaptive system program 108 is stored in persistent storage 508 for access and/or execution by one or more of the respective computer processors 504 via one or more memories of memory 506. In this embodiment, persistent storage 508 includes a magnetic hard disk drive. Alternatively, or in addition to a magnetic hard disk drive, persistent storage 508 can include a solid state hard drive, a semiconductor storage device, read-only memory (ROM), erasable programmable read-only memory (EPROM), flash memory, or any other computer-readable storage media that is capable of storing program instructions or digital information.

Communications unit 510, in these examples, provides for communications with other data processing systems or devices, including resources of mobile device 104, mobile device 106, and cloud computing environment 102. In these examples, communications unit 510 includes one or more network interface cards. Communications unit 510 may provide communications through the use of either or both physical and wireless communications links. Adaptive system program 108 may be downloaded to persistent storage 508 through communications unit 510.

For example, I/O interface 512 may provide a connection to external devices 518 such as a keyboard, keypad, a touch screen, and/or some other suitable input device. External devices 518 can also include portable computer-readable storage media such as, for example, thumb drives, portable optical or magnetic disks, and memory cards. Software and data used to practice embodiments of the present invention, e.g., Adaptive system program 108, can be stored on such portable computer-readable storage media and can be loaded onto persistent storage 508 via I/O interface(s) 512. I/O interface(s) 512 also connect to a display 520.

Display 520 provides a mechanism to display data to a user and may be, for example, a computer monitor.
